MEASURING-PUMP.

Application filed January 9, 1913.

To (17/ whom-1'25 may concern.

Be it known that I', Enwane Kurrnnre, a citizen of the United States of America, and a resident of the city of St. Louis and State of .\lissouri, have invented certain new and useful Improvements in Measuringlump ,ot' which the following is a full, clear, and exact description, reference being bad to the aecoui 'mnying drawings, forming a partof this specification.

My invention relates to a measuring pump provided with an adjustable member for limiting the degree of operation of the pmnp and a sealing device for locking said adjustable member, which may be adjusted and sealed by an authorized inspector of wei hts and measures.

ligurc I is a side elevation, partly in section, of a measuring pum) embodying the features of my invention. Fig. II is a section taken on the line IIII, Fig. I. Fig. III is a perspective view of one of the adjustable members and the seal for locking said member. Fig. 1V is a section taken approximately on the line IV-IV, Fig. III. Fig. V is a horizontal section taken approximately on the line V-V, Fig. VI. Fig. V1 is a vertical section taken approximately through the center of the adjustable members shown in Fig. III.

In the accompanying drawings: A designates a well provided with an intake pipe 1 and an outlet opening 2, a check valve 3 being. arranged in said outlet opening. A pump cylinder 4 mounted on the well A communicates with the outlet opening of said well, and is provided with a discharge pipe 5 at its upper end.

6 designates a vertically movable piston arranged in the cylinder 4, and 7 is a check valve carried by said piston. The piston rod 8 is secured to a rack bar 9 which meshes with a pinion 10. The pinion 10 and operating handle 11 are secured to a shaft 12, journaled in a housing 13. It will now be understood that. the handle 11 and pinion 10 may be operated to reciprocate the rack bar 9, piston rod 8 and piston 6, thereby causing the fluid to be discharged from the cylinder through the discharge pipe 5.

The means for limiting the movement or stroke of the rack bar 9 and parts connected thereto so that. a n'edctermined quantity of fluid will be forced through the discharge pipe 5 comprises a vertical rod 14 and abutments 14 carried by said rod. The upper Specification of Letters Patent.

end of the rod l-l extends through a bearing 15, and the lower end of said: rod is rotatably fitted. to the cylinder head 4. The rod 14 may be rotated by turning a disk 16 secured to the upper end of said rod, and n'ovided with an operating knob 17. A shield 18, which partially incloses, the rod 14, has its ends titted to the cylinder head 4 and housing 13, respectively.

The abutments 14' are formed with extensions I Q, Q, and G, arranged in different horizontal and vertical planes, and adapted to be engaged by-a lug 19 on the rack bar 9. IVhen the abutment P is located in the path of the lug 19, the rack bar S) and piston 6 may be moved upwardly the distance required to discharge one pint of fluid through the discharge pipe When the abutment Q, is arranged directly above the rack bar lug 19, as shown in Fig. I, one quart of fluid may be discharged by moving the rack bar upwardly until it is stopped by the abutment Q. The abutment Q, may be shifted into the path of the lug 19, with the result of limiting the rack bar movement so that two quarts will be discharged durin the upward movement of the rack bar, an the abutment G is adapted to constitute a stop permitting the discharge of one gallon gnring the upward movement of the rack 20 designates a stop carried by the rod 14 for limiting the downward movement of the rack bar.

Each abutment 14 is splined to the rod 14 through the medium of a screw or pin 21 extendin into a groove .22 in said rod, (see Fig. Vi

23 designates a nut screwed onto the rod 14 and having a flange 24 wlnch is confined within the abutment by a threaded ring 25 screwed into said abutment. The abutment may be adjusted vertically by turning the nut 23 and, after the desired adjustment is obtained, the parts may be locked to the rod by a seal. The means I have shown for sealing the parts comprises a wire 26 passing through an aperture 27 in the rod 14, and also passing through oppositely disposed notches in the nut' 23. A seal 28 connects the ends of the wire 2(.

It will be understood that this invention is not restricted to a measuring pump structure having the various details of construction herein shown, the object being to roduce a device which will permit the ant terized inspc toreof weights and measures to tatable 1119111581 screwed onto said rod and sealthe. adjustable parts of a measuring secured to said abutment; and a sealing de- 10 pump. vice connecting said rotatable member to I claim r said rod.
